[Xen-devel] [PATCH 0/4] Display IO topology when PXM data is available

[Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>]

4 patches that add interface for querying hypervisor about device
topology and allow 'xl info -n' display this information if PXM object
is provided by ACPI.

The patches are:

* Store PXM data (nodeID) in pci_dev during PHYSDEVOP_pci_device_add
  hypercall
* Modify XEN_SYSCTL_topologyinfo so that it can return both CPU and
  device topology data. Add corresponding libxl interface
* Use new interface to query the hypervisor about topology and print
  it with 'xl info -n'
* Replace all users of old cpu topology interface with the new
  call. This patch is optional.

Boris Ostrovsky (4):
  pci: Do not ignore device's PXM information
  sysctl/libxl: Add interface for returning IO topology data
  sysctl/libxl: Provide information about IO topology
  libxl: Switch to using new topology interface
